To all whom it may concern:

Be it known that I, CURTIS J. PA'rrnasoN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Processes of -Bread-Making; and I do declare the follow- .which it would ordinarily be capable of a for bleachin preciated so that the baking properties of the flour are not as good as before the treatment. Indeed, the peroxid can be used to such an extent that the elasticity and cohesion of the gluten can be entirely destroyed. J

Accordingto my invention the amount of peroxid in ever case is so small that no appreciable bleac ing will take place. There is no virtue claimed for the material as a bleach, the only eifect beingl to increase the moisture requirement of t e dough batch for a given consistency.

. The amount of peroxid used with a given amount of flour will va in proportion to the percentage of availa le oxyfen resent in the spec' c peroxid employe found by actual experiment that that peroxid has been used dough process it e fol- Specification of Letters Patent. Patented July 26 1921 Application filed March 80, 1921. Serial No. 457,086.

lowing table will be illustrative, the percentage of flour by weight.

' Hydrogen peroxid, H,O,) .0033 Calcium peroxid, 210 .007 Magnesium eroxid, MgO,) .0055 Sodium, 0,) .0073 Potassium, (K 0 .0107.

It is to be understood that the weight of the diflt'erent peroxids employed is in direct proportion to the percentage of the available oxygen present in the compound.

The r uired moisture to be introduced based on into the ou h batch to-rnake the masstof proper consis ncy may vary due to a number of reason the condition of the flour, the quality, etc., all of which can be readily determined by the operator in the process of fiomllilining the ingredients to make the dough atc a i I have found by actual experiment that bread made by my process has higher moisture containing properties than that of bread made by the ordinary method and that, as a result, the keeping properties of the bread are materially enhanced.

The peroxid may be introduced into the dough batch in any convenient manner. It is generally introduced in the form of a powder at the dough sta e of the sponge (if a sponge is prepared) may be mixed along with the other dough constituents and the treat ment of the dou hmay proceed in the usual manner. Ifhy rogen peroxid is employed, it should be combined with the waterentering the dough batch. The other forms of.

peroxid, being solids, are preferably introduced at the dough stage of the sponge as above described.

I have demonstrated by actual practice that there is no change in the fermentation due to the inclusion of peroxid in a proxi mately the propgrtions specified, t e ad-. yanta eclaimed tent o the dough may be increased and as .a result, the finished loaf will remain moist for a longer period than is possible with bread made according to known methods and that the peroxid causes the gluten to absorb the water without destroys-3g the elasticity of the dougbrthe resul t product being a ing that the moisture conut in the straight well formed loaf having better keeping qualities than the ordinary loaf.

What I claim and desire to secure by Letters-Patent is:

1. The step in the process of making bread which consists in lncorporating wlth the flour and other ingredients of the dough batch, peroxid in such "quantities as will in crease the moisture capacit of the dough batch above the normal wlthout breaking down the gluten in the flour, such peroxid bein non-toxic to permit its use in a food pro uct.

2. The step in the process of making bread which consists in lncorporating with the flour and other ingredients of the dough batch, hydrogen peroxid in such as will increase the moisture capacity of the dou h batch above the normal without brea ing down the gluten of the flour.

In testimon whereof I aflix m signature.
